Precise Position Measurement with Rotary Sensors

What do washing machine program selectors and the adjustment of headlights or windshield wipers in cars have in common? In all these applications, rotary sensors are used to precisely detect rotational movements.

The measurement of the rotation angle is often performed contactlessly using the Hall effect. A magnet’s position is detected without any mechanical contact with the sensor. The key advantages: no wear, long service life, and reliable operation even under demanding conditions.

Another benefit is absolute position measurement. Even in the event of a power drop, the last set position is retained. After restarting, there is no need to return to a reference point.

Metallux rotary sensors POH 120 and HMS 220 feature a compact, robust design and freely programmable angle ranges. They are ideal for a wide range of applications in industrial, automotive, and household environments.
